The James Paget University Hospital, in gorleston, tweeted: “Despite the snow, it is very much business as usual at our hospital today. Outpatient clinics/procedures are going ahead as scheduled so please attend your appointments as planned. However, if you can’t make an appointment, please let us know as soon as possible.”

Public Health England’s extreme events team issued a health warning ahead of the cold snap.

Dr Thomas Waite, on the team, said: “Cold temperatures, indoors and out, pose real health risks to many and every winter we know that thousands of people get ill and even die following exposure to cold conditions.

“As forecasters tell us [this] week temperatures will fall, it’s critical that if you know anyone over 65, with young children or who has heart or lung conditions, that you keep an eye on them and think what help they may need. Staying warm by heating your home to at least 18°C can be crucial to stay well.”
